The ball will hit the ground
6.06 seconds
after thrown.
How many seconds does it take the ball to hit the ground?
It takes
three seconds
for the ball to hit the ground.
How do you find the time when the ball hits the ground?
- Determine the gravitational acceleration. …
- Decide whether the object has an initial velocity. …
- Choose how long the object is falling. …
- Calculate the final free fall speed (just before hitting the ground) with the formula v = v0 + gt = 0 + 9.80665 * 8 = 78.45 m/s .
How do you figure out when an object will hit the ground?
- Determine the gravitational acceleration. …
- Decide whether the object has an initial velocity. …
- Choose how long the object is falling. …
- Calculate the final free fall speed (just before hitting the ground) with the formula v = v0 + gt = 0 + 9.80665 * 8 = 78.45 m/s .
How can I get my height after t seconds?
After t seconds, the height of the ball is given by the equation
h=-16t^2+55t+6
.
How long will it take for the ball to hit the ground physics?
So it takes
barely a second
for the ball to hit the ground from that height.
How do you find free fall?
- Determine the gravitational acceleration. …
- Decide whether the object has an initial velocity. …
- Choose how long the object is falling. …
- Calculate the final free fall speed (just before hitting the ground) with the formula v = v0 + gt = 0 + 9.80665 * 8 = 78.45 m/s .
Do heavier objects fall faster?
Heavier things have a greater gravitational force
AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.
How far do you fall in 2 seconds?
The first equation shows that, after one second, an object will have fallen a distance of 1/2 × 9.8 × 1
2
= 4.9 m. After two seconds it will have fallen
1/2 × 9.8 × 2
2
= 19.6 m
; and so on.
How can I calculate my height?
To get your height in inches alone from the way it's usually presented (e.g. 5′ 7′′),
multiply the total number of feet by 12 and then add the remainder
. For example, a 5′ 7′′ person is (5 × 12) + 7 = 67′′ tall.
How many seconds does it take to reach maximum height?
It takes about
88 seconds
for the cannonball to reach its maximum height (ignoring air resistance). You have 176 seconds, or 2 minutes and 56 seconds, until the cannonball destroys the cannon that fired it.
How high is the ball after 3 seconds?
After 3 seconds, the height of the ball is
150 feet
.
How far do you fall in 6 seconds?
The formula I learned in high school Physics is s=1/2gt squared, where s is distance in meters, g is the force of gravity (10 meters per second per second), and t is time in seconds. So in 6 seconds, a person will fall
5 x 36 or 180 meters
.
What are the 3 kinematic equations?
Our goal in this section then, is to derive new equations that can be used to describe the motion of an object in terms of its three kinematic variables:
velocity (v), position (s), and time (t)
. There are three ways to pair them up: velocity-time, position-time, and velocity-position.
